  • Applications

    N,N-Dimethyl-1-octadecanamine-N-oxide (CAS 2571-88-2) is a long-chain fatty amine oxide that functions primarily as a nonionic surfactant and emulsifier in a range of formulations; typical applications include household and industrial detergents and cleaners where it contributes wetting, foaming, and cleansing performance; it is used in personal care products such as shampoos and facial cleansers as a mild surfactant and conditioning aid; in coatings, inks, and polymer formulations it acts as a wetting agent and pigment dispersant to improve stabilization and dispersion; it may also serve as an intermediate or building block for the synthesis of specialty surfactants and lubricant formulations, subject to local regulations and formulation limits.
